If you already have a solar PV system, now is the perfect time to upgrade with battery storage. The UK government’s VAT exemption on retrofit battery storage means you can save on installation and product costs if you act before March 2027. With battery technology advancing rapidly and prices becoming more affordable, upgrading your system has never been more rewarding.
At Wagner Renewables, we’re more than just solar experts: We’re Tesla-approved installers and a UK distributor for GoodWe products, offering you industry-leading solutions tailored to your needs.
Battery storage systems store surplus energy generated by renewable sources like solar PV. When your solar panels produce more energy than your home uses, the excess is typically exported to the grid. With a battery storage system, this energy is captured instead. When your energy usage exceeds what your solar panels produce, the stored energy is used, reducing reliance on the grid.
There are two main ways to integrate battery storage with solar PV systems:
While the equipment differs slightly, both methods offer effective solutions tailored to your needs.
Battery storage systems are a game-changer for solar PV users, capturing surplus energy your panels generate and saving it for later use. Instead of exporting excess energy back to the grid, you can power your home or business at night or during peak energy demand, reducing your reliance on imported electricity and cutting your bills.
Modern battery storage systems, such as GoodWe and Tesla Powerwall, allow you to charge your batteries during off-peak hours. By leveraging time-of-use tariffs, you can maximise efficiency and cost savings.
Here’s how it works:
This strategy ensures you get the most out of your solar and battery system.
Adding battery storage will not impact your FIT payments. Your FIT contract remains intact for its duration. However, you might explore switching to the Smart Export Guarantee (SEG) if your energy supplier offers competitive rates for exported energy.
Keep in mind that once you cancel your deemed export contract, it cannot be reinstated. Ensure SEG rates make financial sense before switching.
As of February 1, 2024, the government has expanded the zero VAT scheme to include:
This exemption will remain in effect until March 31, 2027, after which the VAT rate for Energy Saving Materials (ESMs) reverts to 5%. It’s essential to have the installation completed by a qualified professional to qualify for VAT relief.
